' CLAMPlNG-BAND;

? QToaZZ whom it may concern:

-.Be' it known that I, LEO A. RosrER, a citi zen of the United Statesof America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Clamping-Bands, of which the following is a specification, ref- I erence being had therein to the accompanying drawings. I

This nventlon relates to lmprovements n clamping-bands for. embracing and detachably securing two parts of an article orvessel together or for'securing the cover to the body 'of a can, ar, crock, &c., and more especlally to the means for drawing the ends of the band toward each other to clam the same about the article and for detacha ly holding space 'Will'beleft between its adjacent ends,-

the band in its clamping'position.

- Theprinci'palfobject of the invention is to provide a fastening for this purpose. which may be adjusted to increase or decreasethe nearness with which the ends of the band will be drawn'together to vary the clamping power of the band, and which means may be quickly and easily operated to release the -A further object of the invention is topro- VldB a clamping-band which may be removed from the article laterally, thus obviating the necessity of slipping it down overthe same, and to-provide a fastening for the band which is strong anddurable and is provided with' certain other new and useful features, all as hereinafter more fully described, reference being had to the accompanying drawings, i n

Figure 1 is an elevation of a device em.- bodying the invention with parts broken away'to show'the construction. Fig. 2isan edge .view' of the band, and Fig. 3 is a central lon itudinal section through the fastening an a portion of the band. f

As shown in the drawings, 1 is a clampingband formed of sheet metal rolled into a 'cir cular form, with edge 'ortio'ns or flan'g'esZ. bent or. inclined inwar to engage shoulders, flanges, or other rejections upon the two .Earts-of the artic e to beclam ed together said band, the inclines ten ing toforce t e arts firmly toward each other.- The closely about thearticle by the fastening 3 a and near'one of said ends the metal of the bandis struck up to form two parallel hooks 4, extending outward at :rightangles to the Specification of.

band, and the oppositeend of the band is provided with outwardly-extending parallel ears 5, formed in like manner. The ears 5 are provided with openings to receive the later ally-projecting trunnions 6 on the end of a lever 7, which is formed of sheet metal and provided with outwardly-extending ears 8 intermediate its ends formed by bending projecting edge portions of the metal at right angles to the outer face of the lever. Open" ings are formedin the ears 8 to receive the laterally-extending round bearing ends on a T-head 9, formed integral with a connectingrod 10, which is screw-threaded at its opposite end to engage a screwthreaded opening in a block provided with laterally extending rounded arms, forming an adjustable crossbar, 1 1, adaptedtobe engaged with the hooks 4, The connecting-rod 10 is so arranged that when the "cross-bar 11 is engaged with the hooks and the clam ing-lever 7 is thrown back against theban as shown in Fig. l, to draw the band about the article said rod will engage .the band inter-mediate its ends and be sprung slightly, so that the tendency of the'rodwill be to turn the lever on .its pivots away from the band, and thus release the same. .A spring-catch 12 is'thereforeprovided to engage the free end of the lever and hold the same in its clamping positidn, said catch being formed by severing a portion of the metal of the band and bending the cutout portion outward at right angles, at the same time forming a'slight projection 13 in the center of said portion to engage the ends of the lever and'hold the same. .fThe'lever'is thus caught and held by the catch when forced into engagement with'the band, and

when it is desired to remove the band the same will be released by'simply sprin ing the catch slightly, the lever, being turne by the rod to disengage the cross-bar from the hooks. When thelever is turned and the cross-bar disengaged from the hooks, the ends of the band are no longer connected and may be sprungv a art to disengage the flanges frome band and the slack taken widely separated when the fastening is re- I leased, thus ermitting the band to heremoved latera ly without dan er of injuring the same by springing it too ar and obviating the necessity of slipping the band Over the article when it cannot be. sprung far enough to take the article in between its ends. When the parts become worn by use or from any othercause, the throw of the lever becomes insufficient to draw the band with suflicient force about the article, the crossbar may be adjusted on the connecting-rod,

u Having thus fully what I claim is l 1. The combination of a circular clampingband, a lever ivotally attached at one end to one end of said band, and means pivotally attached to said lever and adapted to be endescribed my invention,

'gaged with and disengagedfrom the opposite end of said band.

2. The combination of a circular clampingband, a lever pivotally attached at one end to one end of said band and means for engaging the opposite end of saidband and pivot ally connected to said lever, adapted to be adjusted to bring its point of engagement fvith the band nearer the pivoted point of the ever. f

i 3. The combination with a circular clamping-band, of a lever pivotally attached at one end to one end of said band, a connectingver and screw-threaded at its opposite end,

rod pivotally attached to said lever, and

means adjustableon said rod for engaging the opposite end of the band.

4. The combination wlth a circular clamping-band, of a hook on one end of'said band,- a:

lever (pivotally attached to the opposite end ofsai band, means attached to the lever for engaging the hook, and a sprin -catch on the band to engage the lever and old the same in its operative position.

5. T e combination with a, circular cla'mping-band, of parallel hooks on one end of said band, a lever pivotally attached atone end to the opposite end of said band, a connectingrod pivotally attached at one end to said lesl tes and a cross-bar having a screw-threaded opening to receive the screw-threaded end of the rod adapted toengage the said hooks.

6. The combination with a circular clamping-band, of hooks on one end of said band, ears on the opposite end of said band, a lever pivoted at one end to said ears, a connectingrod pivoted at one end to the lever intermediate the ends thereof and adapted to engage the hooks at its 0 posite end and to engage the banddnterme iate its ends'to turn the le-' ver on its pivot, and as ring-catch on the band to-engage and hold t e lever.

7. The combination with a circular clam ing-band formed of sheet metal, of parall el hooks formed at one end of said band, parallel ears formed at the opposite end of said band and each provided wlth an opening, a lever provided with laterally-projecting trunnions to enga e the o enings in said ears, a connecting-r0 pivota ly attached to the lever at one end, a cross-bar adjustably secured to the rod to engage the hooks, and a spring-catch to engage the free end of the lever.

8. The combination of a circular clampingband made in halves and formed of sheet metal with inwardly-inclined edge flanges, means pivotally connecting the ends of said halves at one slde, hooks formed on one end .of said band, ears on the opposite end of said band, a lever provided with laterally-projecting trunnions engaging openings in the.

ears, ears on the lever intermediate its ends,

'a connecting-rod screw-threaded at one end and provided with a T-head at its op osite end to engage openings in the ears on t e lever, a cro'ss-bar having a screw-threaded o ening to receive the screw-threaded end of t e connectin -rod and ada ted to engage the hooks, an a spring-catc on the band having a projection to engage the lever.

In test mony whereof aflix my signature in presence of two witnesses. LEO A. ROSIER.
